一,产品概述(General Description) 
The CXLD6474 dual, low noise, low-dropout regulator supplying up to
300mA output current at each channel. The output voltage for each
regulator is set independently by trimming. Voltages are selectable
in 50mV steps within a range of 1.2V to 3.3V by operating from a 2V
to 6V input. The CXLD6474includes two independent logic-controlled
shutdown inputs and allows the output of each regulator to be turned
off independently. When both outputs shutdown simultaneously, the
chip will be turn off and consumes nearly zero operation current which
is suitable for battery-power devices.
The CXLD6474 includes high accuracy voltage reference, error
amplifier, current limit circuit and output driver module.The CXLD6474
has excellent load and line transient response and good temperature
characteristics,which can assure the stability of chip and power
system.And It uses trimming technique to guarantee output voltage
accuracy within ±1% or ±2%. The CXLD6474 is available in SOT-23-6 and
ESOP-8 package which is Lead(Pb)-free
